1991 or 92 Hobbytown in Vista, Ca. It was an indoor offroad track 100' x 60', when it first opened we would have 75+ entries! I was lucky to make the B if not the C main in stock buggy. A lot of the local Associated and Traxxas team guys raced there (yes, Traxxas used to have race cars and sponsored A LOT of people).
Interest dwindled and within 2 years it wasn't making money and it was shut down, now it's a brake and tire shop.
A few years later I helped Hobbytown San Marcos start a parking lot racing program. We ran offroad cars with plywood jumps, F1 cars with silver can motors (biggest class, usually 30+ entries), Bolink diggers (FUN!!), Touring Car (new class, not many chassis' available. Yok YR4 was the spark that started that class), 10th pan car, and Nitro Touring Car later on (HPI nitro RS4). Those were the best times I ever had racing. Get to the track at 6AM to blow all the dust off the parking lot. Set up the fire hose and metal corner dots. 10AM start taking signups (usually 80-100 entries), enter all the names in the computer and HAND COUNT cars all day. Yup, no transponders, when you see a car go by you press the number on the keyboard! We had to get done with racing by sunset (no lights), then tear it all down and pack everything into the store's storage space. Normally I would get home at 8 or 9pm, but hey I usually made $30 or $40
